It's a little out of focus, I think the camera was focusing on your thumb and not the crystal but it looks to me like it is a milky quartz crystal.

I have a lot of rocks on my farm and I was out pounding fence post yesterday and decided to pound a couple of rocks and found these inside, I am a total rookie but I was kinda excited. Kenneth

Beryl is hexagonal (6 sided). If you can get a picture looking down from one end, it may help.

I have seen beryl formed with 4 sides, 5 sides, weird sides. Some amethyst in geodes from brazil don't even have sides but only have a 3 sided pyramid for a crystal. Shape is really the worst way to identify a mineral but it is the easiest especially for a preliminary guess. here is a beryl crystal handdug out of the ground. It's as is just like it was formed in the ground(minus slight weathering due to ground water) You can see on the bottom right the 4 sides of the crystal but the rest is a mish-mash of surface area.  The sides of the crystal with the vertical striations show how it formed in the ground with no sides..so to speak  So with no discernable traits, trying to identify your crystal without any other test done is a big step but we have quite a few folks on here who are pretty good at that. Like dwt said it looks like fledspar |

i agree Amethystguy, there's a lot more to i.d.ing things than just crystal shape. I was just generalizing. I've got enough Herkimers to prove anything is possible for crystal shape!  |

Here is another example I posted a while ago. First inclination would be beryl...nice well developed six-sided crystal I would have guessed beryl like everybody else but ... it's tourmaline which is trigonal and hexegonal. Your right crystaldigger even when you get into quartz which is the most studied rock there are still suprises and new discoveries  |
